Distinguishing Features: The archetypal penguin that looks like a man in his dinner suit. The simple plumage ensures good camouflage against predators (black back against the dark depths of the sea, and white belly against the bright sea surface above).

How They Got Their Name?: They were named from Adélie Land, where they were first scientifically described in 1840 by French explorer Jules Dumont d’Urville, who named this portion of Antarctica in honor of his wife, Adelie.
